Let's suppose you deploy a network-attached appliances (small form factor PCs) in the field. You want to allow these to call home after being powered on, then be identified and activated by end users.
Our current plan involves the user entering the MAC address into an activation page on our web site. Later our software (running on the b...

We help our clients to manage and publish their media online - images, video, audio, whatever. They always ask my boss whether they can stop users from copying their media, and he asks me, and I always tell him the same thing: no. If the users can view the media, then a sufficiently determined user will always be able to make a copy. ...

I was asked implement a licensing schema for our product. They are very expensive products with few customers sparsely distributed around the world and basically every one of them has a design environment (a windows application installed on single windows machines, from 1 to 150 client machines per customer) and a web server that hosts ...

Anyone visiting a torrent tracker is sure to find droves of "cracked" programs ranging from simple shareware to software suites costing thousands of dollars. It seems that as long as the program does not rely on a remote service (e.g. an MMORPG) that any built-in copy protection or user authentication is useless.
Is it effectively not ...

I would like to set up some WMV Video Streaming, using Windows 2003's Streaming Media Server and Silverlight.
Now, unfortunately Silverlight only supports HTTP, which means that people can just download the videos. While that in itself is not a problem, I wonder what options there are to prevent them being playable outside of the networ...

Is it possible to protect flv files from download? I'd like to protect my files from download but I don't have the money for a streaming server which I think provides some sort of protection. The files are streamed via PHP and are located in an upload folder on my server.
I've used PHP to ensure that only subscribers can view the video ...

I have a project that needs to play video but not allow downloading.
I'd love to use Flash, but I've seen applications that let you download files from YouTube -- this makes me wonder if Flash isn't that secure.
Must I use Quicktime or Windows Media?

Obeying NDA restrictions I have to be vague.
I've been tasked to evaluate the feasibility of forcing a .dm file from my client's system to a cellular device. So far I know I can send a smil payload with a txt & gif|jpg payload but not a .dm file.
Inside of the DRM wrapper there is a header prefix before the payload starts.

My client wants to encrypt/compress the html-code for their medical books in the iPhone bundle, to protect their IP.
Whats is a good way to prepare this file for the app bundle, and what complementary libraries (C, Obj-C) should I use to do the decryption and decompressing on the first launch of the app?
Copying the file to ~/Documen...

How can we restrict a user from saving the page?
Please provide some tips to disable File->Save and View Source options
EDIT: Obviously it can't be done, and probably shouldn't be attempted. But possibly a more interesting variant on this question is how can we make is sufficiently hard for a user to save a page in a usable format suc...

Hi,
I have a program that is using a configuration file.
I would like to tie the configuration file to the PC, so copying the file on another PC with the same configuration won't work.
I know that Windows Activation Mecanism is monitoring hardware to detect changes and that it can tolerates some minor changes to the hardware.
Is the...

Is it possible to legally progressive play Windows Media DRM tracks as they are downloaded from a HTTP link?
I've managed to do this without DRM but someone here told me it wasn't possible with DRM. Is this true?
And if so with what set of libraries or technologies?

On March-26-2009 a Slashdot article discussed the March-25 press-release of Stardock's ImpulseDriven DRM-for-code system.
Up till today I have belonged to the DRM-intrinsically-hopeless camp. Having glanced over all 9 pages of stackoverflow articles on the DRM tag I noted that e.g. PAX and SIMUCAL offer eloquent posts indicating that th...

Same intro as my last question:
I am re-writing and/or consolidating a bunch of my "app framework" classes (basic mainform, about box, locking routines & purchase linking, auto-update, datamodule initializer, etc) -- Basically, I have a number of small potential shareware apps that I'm wanting to get out the door, and want to re-use cod...

The Apple QuickTime standalone player can manage iTunes' DRM scheme well enough to play movies downloaded from iTunes with no problem. Is there any way to get QuickTime for Java to handle iTunes DRM similarly well, or is that simply beyond the software's abilities?

I am curious to know if anyone has figured out a way to create the server portion of DRM in an open source manner while allowing for DRM clients to be closed. I understand that if the client were open source, it would be easy to remove the DRM checks, but I believe the server doesn't suffer from the same challenge.

Is there some open-sourced, well-documented and used DRM framework/library?
I want to write some framework for buying and selling digital stuff, where I want to implement, somehow, for the seller to have the possibility to lock the files with some sort of DRM, where only authorised computers would be able to open it (something like iTun...
